A method is disclosed comprising obtaining or acquiring image or other data from one or more regions of a target using an imaging sensor. The image or other data may then be used to determine one or more regions of interest of the target. An ambient ionisation ion source may then be used to generate aerosol, smoke or vapour from one or more regions of the target.

An instrument for large-area ablation of the mucosa including at least one first gas supply line and at least one second gas supply line whose distal ends are arranged to form an acute angle (), so that the ends diverge distally. A free space between the distal ends of the gas supply lines allows the user to view the tissue region behind the distal end of the instrument. Due to the acute angle (), electrodes arranged at least partially in the ends of the gas supply lines generate a wide plasma beam with which the mucosa ablation can be performed. The instrument can be guided precisely due to the view through the free space. A connecting element according to the invention is provided for attaching the ends of the gas supply lines.

A vapor delivery system and method is provided that is adapted for ablating bladder tissue to treat overactive bladder (OAB). The vapor delivery system includes an anchor tip configured anchor the system in the bladder while condensable vapor is delivered to target tissue. In one method, the vapor delivery system is advanced transurethrally into the patient to access the target tissue of the bladder, which can include a surface sensor of the bladder responsible for creating an urge incontinence sensation. The vapor delivery system includes a vapor source that provides a high quality vapor for delivery to tissue.

The laser lancing device in accordance with an exemplary embodiment includes: a main body; a laser resonator located within the main body and configured to generate a laser and output the laser forwards; a beam barrel located in front of the laser resonator and including at least one lens unit fixed therein; a window barrel located in front of the beam barrel and connected to the main body; a cap part connected to the front of the window barrel and brought into contact with an irradiation target area; a fan unit communicating with the cap part and induce flow of air; and a communication pipe of which one end is connected to the fan unit and the other end is connected to the cap part.

A cautery device includes an elongated handpiece extending axially from a proximal end to a distal end and a cautery tip extending coaxially with the handpiece from the distal end of the handpiece. The tip defines a channel extending coaxially with the handpiece along at least a portion of the length of the cautery tip from a proximal open end to a distal end. The device includes a gas supply connection extending from the proximal end of the handpiece for supplying gas to the cautery tip. The gas supply connection is fluidly coupled to the cautery tip. The device includes an electric supply connection extending from the proximal end of the handpiece for supplying electricity to the cautery tip. The electric supply connection is electrically coupled to the cautery tip. The gas supplied to the cautery tip is introduced to the channel at the proximal open end and exits to envelop the distal tip.

Ultrapolar non-telescopic electrosurgery pencil with argon beam capability which is capable of using monopolar energy in a bipolar mode for cutting and coagulation and which is also capable of using an ionized gas for cutting and coagulation.

The present invention teaches minimally invasive apparatuses and methods for stabilizing and/or guiding medical instruments used in a variety of medical procedures, including (a) introducing one or more substances into a subject's body, (b) removing one or more substances from a subject's body, (c) manipulating a region of a subject's body, or (d) combinations thereof. Among the many advantages of the inventive apparatuses are their simplicity and adaptability to attach to a variety of retractors.

A surgical system includes a control assembly and a surgical instrument defining a gas inflow path, a gas outflow path, and an end effector configured to apply energy to tissue. The control assembly includes a gas output configured to connect to the gas inflow path, a gas input configured to connect to the gas outflow path, and an energy output configured to supply energy to the end effector. The control assembly further includes a controller to determine an amount of gas output from the gas output, determine an amount of gas withdrawn into the gas input, compare the amount of gas output and the amount of gas withdrawn, and control withdrawal of gas from the gas outflow path such that the amount of gas output and the amount of gas withdrawn are equal to one another or within a threshold margin of one another.

An electrosurgical device having an electrode with a first portion whose exterior is electrically uninsulated, a second portion whose exterior is electrically insulated, and a third portion. An elongated hollow body has an internal cavity, a front end, a rear end, an external surface. An electrical circuit is arranged within the body. The second portion of the electrode is not surrounded by the hollow body. A first button is arranged on the external surface of the body for controlling a current flow at a first level. A vacuum tube is slidably engaged by the body. A vacuum outlet port is arranged near the rear end, and the outlet port, internal cavity, and vacuum inlet are in fluid communication with each other.
